Concept of transitional arteries
The transitional zone is a segment of the
arterial tree, where elastic-type wall
architecture is relayed by one of muscular
type. Transitional arteries are characterized
by a different ratio of scleroproteins
(elastin,collagen) and vascular smooth
muscle cells in the tunica media (Janzen
2004).
